It's not the heat; it's the lack of humidity.

"Hey Sara, what you up to? Going camping or something?"

No, just stocking up on supplies. I'm going into hibernation.

"Hibernation? But it's the beginning of May. It's absolutely gorgeous outside."

Exactly. When I lived in the Midwest, it was so hot and humid, it was like breathing soup. God I miss it.

"That sounds miserable. You actually miss that?"

You have no idea. Anyway, if you need me, I'll be in the basement with my PureGuardian Ultrasonic Humidifier turned up to full blast.

"For how long?"

At least 120 hours, until I need to refill the tank.

"Aren't you worried you'll get mold?"

Nah. It uses Silver Clean technology to fight the growth of mold and mildew.

"Well, then aren't you worried you'll get swamp ass?"

What's that?

"You know when it's really hot and humid, and your jeans stick to the back of your legs and your butt gets all saggy and soggy."

Oooh. Yeaaaaaah.

"There is something really wrong with you."


"Hey wait. Why don't you just get a humidifier? I have one of those PureGuardian Ultrasonic ones with Silver Clean technology.
